Quantum teleportation is, indeed, possible. For the first time in history, two separate teams of scientists successfully performed to perform the teleportation in the real world and not just in the lab.
First off, the teleportation is a phenomenon that occurs when quantum information is transported from one particle to another without these particles meeting. This process relies on entanglement, where no matter what distance, the quantum state affects its entangled partner.
In a promising scientific breakthrough, two independent teams were able to transport quantum information over a number of kilometers of fiber optic networks. The findings of the new teleportation experiment outside of the laboratory were published in the journal Nature Photonics.
From The Labs
The teleportation we are talking about here is not the same as what we saw Scotty do in Star Trek. However, the phenomenon is still very astonishing, especially because it happens in real life.
Teleportation has been tapped for ages by many scientists. In 1977, two particles were transported in an 800-meter distance in the same laboratory.
Additionally, in 2012, teleportation was also successfully done for two particles in two separate locations in the Canary Islands with the record distance of 143 kilometers (88.8 miles). This was also done in a laboratory.
To The Real World
While the existence of quantum teleportation is already proven to be true, it was not yet done outside the controlled environment of laboratories. But that is changed when two separate teams of researchers from Canada, Calgary, and Hefei, China were able to successfully conduct the teleportation in the real world.
With the use of their city’s existing fiber-optic cables, the separate teams were able to send photons from each other. From the Calgary team, they sent 17 photons per minute at distance of around 6.4 km, or around 4 miles.
Meanwhile, the teleportation by the team in Hefei was done at a slower rate for a distance of 14 km or 9 miles. They got an average of 50 percent of correctly determined photon state, while Canadians got 25 percent.
The success of these experiments is a great milestone for quantum teleportation and its many potential applications, including a safer data encryption.
